BMS掉电检测保护电路
By designing a BMS power failure detection and protection circuit, a voltage clamping and delay circuit is used to quickly respond to power failure and automatically shut off the main power circuit switch, thus solving the Miller plateau problem when the BMS fails and improving system reliability and the lifespan of the main power circuit switch.
